This test does a check on all thermistors, fans, and defrost circuits. The thermistor test will display pass, open or
shorted. The fan and defrost tests will display pass or fail. Once this test is invoked, the test mode will stop flashing
and the numbers from 1 to 10 (corresponding to the chart below) will appear on the HMI display.
For each test, the HMI will respond by displaying the following:
P = Pass
F = Fail
O = Open Thermistor Circuit
S = Short Thermistor Circuit
The control will display a O if the thermistor value is greater than 149.2K &! (-58°F (-50°C)). The control will display
a S if the thermistor value is less than 1.34K &! (149°F (65°C)).
Note #4 (100% Run Time)
This test runs the sealed system 100% of the time and will automatically time out after 1 hour. Cycle power OFF or
enter test mode
1 5 to reset and exit this mode.
Note: The 3-way valve position during 100% run time depends on the fresh food temperature. If the fresh food
temperature is satisfied, the 3-way valve opens to the freezer evaporator only. If it is not satisfi ed, the valve opens to
the fresh food evaporator and refrigerant flows through both evaporators.
Note #5 (Toggle the State of Defrost)
Any time a pad on the temperature board (other than the COLDER and WARMER pads) is pressed, the status of the
defrost heaters will toggle in the following sequence:
1.
Fresh food heater ON.
2. Fresh food and freezer heaters ON.
3. Fresh food and freezer heaters OFF.
Pressing the pad a fourth time will cycle through the sequence again. During the sequence, heater current can be
measured.
• Fresh food heater - approximately 1.2 amps when measured at the CN01 connector black wire.
• Fresh food and freezer heaters - approximately 4 amps when measured at the CN01 connector black wire.
